I don't know if it's normalespecially if you only have it with just one eye.
I have something like that, I just thought my eyes were very sensitive to lights.
When I go outside or even a room were the lights are bright my eyes hurt and I can't see well (like what you said, like the colors are washed out, everything is just really bright - too bright to look at) than when I go inside, or a darker room it takes some time for my eyes to stop hurting and the color to come back fully. Wearing sunglasses doesn't even help. I have to drive with sunglasses even on cloudy days. If I'm in the bright lights for more than just a minute I get an awful headache also. It's at the point now that if I'm going to be outside or shopping in a brightly lit store I take RX pain meds first to keep the up coming headache from getting to bad.

I would defiantly talk with you Dr about it. With it being new and only in one eye it doesn't sound normal to me.
